Title: Automatic balancing apparatus
Inventor: ANDO MASANORI
IPC: G01R27/02
Filed: 1990-11-30
Abstract: PURPOSE:To enhance current detecting accuracy and to provide a highly accurate impedance meter from a low-frequency region to a relatively high-frequency region by providing a compensating signal generator. CONSTITUTION:In this automatic balancing apparatus, a DUT 1 as a sample, a reference resistor 3 as a reference element and an operation amplifier 6 as an amplifying means are provided. A compensating signal generator 20 as a compensating means for generating the compensating signal which is approximately same as the output signal of the operation amplifier 6 is provided. An adder 30 as an adding means is provided. The load of the operation amplifier 6 is alleviated. The potential of the connecting point P between the DUT 1 and the reference resistor 3 is brought close to the ground potential. At the low frequency where the compensation is not required, a switch 21 is opened, and the compensating signal generator 20 is isolated. Thus the time required for the compensation operation of the compensating signal generator 20 can be saved. When stray admittance Yp is large even at the low frequency, the compensating signal generator 20 is operated, and the current detecting errors can be decreased.

Title: Automatic setting method for terminal address
Inventor: FURUKAWA HIDEKI
IPC: F24D3/00
Filed: 1991-12-20
Abstract: PURPOSE:To prevent generation of an input miss and to attain efficient address setting by automatically setting up a terminal address. CONSTITUTION:At the time of receiving a request signal from a center 1, each of terminals 2 to 4 checks no communication of other terminals after a fixed time determined in each terminal at random and sends a machine sort code and the fixed time set up at random to the center 1 through a common address. The center 1 executes the parity check of these data, and after confirming no overlap of plural terminals, allocates and stores an address and communication queue time and informs these data to the terminal. The terminal stores the address and the queue time and automatically sets up them so as to execute succeeding communication in accordance with the set contents. Consequently the overlap of addresses or the generation of a working miss can be prevented and the quantity of working can be reduced.

The voltage of a power system 1 is measured by a transformer 5, and a current on the side of a load in the injection point (a) of the system 1 is measured by a current transformer 6. Then, the analog measured output of the current transformer 4, that of the current transformer 6 and that of the transformer 5 are converted into digital signals by an A/D converter 7 in a harmonics measuring apparatus so as to be supplied to a signal processor 8. The processor 8 analyzes digital frequencies of the measured outputs by the current transformers 4, 6 and the transformer 5 so as to detect the voltage and the current of the system 1. In addition, the analyzed result of the processor 8 is supplied to a processor module 9. The processor module 9 subtracts the vector of a noise, and it computes a harmonics characteristic.
